[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 2%@4]  
#Z`q+@@]A  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： ,+vy,<e&  
enableservice('AutomationServer', true) m=A(NKZ  
enableservice('AutomationServer') ~tUl}  
," Wr"  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 iWB=sL&p

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： k,E{C{^M  
1. 在FRED脚本编辑界面找到参考.
QP^Cx=  
2. 找到Matlab Automation Server Type Library 3kIN~/<R+7  
3. 将名字改为MLAPP 1s2>C!\

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 4Lh!8g=/

现在将脚本代码公布如下，此脚本执行如下几个步骤： ox>^>wR*  
1. 创建Matlab服务器。 #ASz;$P  
2. 移动探测面对于前一聚焦面的位置。 Y1OkkcPb{  
3. 在探测面追迹光线 *:YiimOY"  
4. 在探测面计算照度

5. 使用PutWorkspaceData发送照度数据到Matlab 3yY}04[9<  
6. 使用PutFullMatrix发送标量场数据到Matlab中 1i"WDu*h3  
7. 用Matlab画出照度数据 D>@I+4{p  
8. 在Matlab计算照度平均值 +0%w ;'9z  
9. 返回数据到FRED中 tl4V7!U@^z
